of orangutans at Samboja Lestari unable to be reintroduced into the wild due to physical disability, chronic illness, abnormal behaviours, or a lack of survival skills, the BOS Foundation has also developed facilities specifically to provide lifelong sanctuary care for these individuals. These facilities vary from sanctuary islands for orangutans who are not severely disabled and capable of living in almost natural conditions with minimal human support, to a Special Care Unit for those who need frequently and regular veterinary support. Sun Bear Sanctuary At the request of the Indonesian Government, Samboja Lestari became home to over 70 sun bears, confiscated from the illegal pet trade or rescued from deforested areas. As there is no standardised, proven method of reintroduction for sun bears, the BOS Foundation provides instead lifetime sanctuary care in semi-wild conditions. The sanctuary includes a area put aside for the bears including a 15 fully forested enclosures with attached dens, varying in size from to . Ecotourism The Samboja Lodge was established to provide accommodation for visitors and volunteers at Samboja. Its design was based upon local architecture and its interior and exterior walls are made of recycled materials. Visitors to the lodge, whether staying overnight or just for a single day, are educated in the importance of orangutan and ecosystem conservation by guided tours of the neighboring orangutan sanctuary islands and sun bear sanctuary. The profits from overnight and day guests help to fund the conservation activities undertaken by the BOS Foundation at Samboja Lestari. Project Impact Although there is not yet a return to the full biodiversity of the rainforests of Borneo, a secondary forest is growing which it is hoped will eventually become a safe haven for all of Borneo's biodiversity. According to Smits in his 2009 TED talk in addition to bird species such as hornbills, 30 species of reptiles, porcupines, pangolins, mouse deer and many other animal species have been recorded. The orangutan rehabilitation program at Samboja Lestari started selecting orangutans with adequate natural behaviours to be released into the Kehje Sewen Ecosystem Restoration Concession, owned by PT Rehabilitasi Orangutan Borneo, which is also operated by the BOS Foundation. In April 2012, They released their first 3 orangutans from Samboja Lestari in the Kehje Sewen ERC. Today, 121 orangutans from Samboja Lestari have been released back into the wild (per July 2021).
